Socket io enables real time bidirectional and event based communication.
Socket io rooms limit.
When a user connects they automatically join the room that i have setup.
It should be noted the socket doesn t relate directly to the actual underlying tcp ip socket and it is only the name of the class.
Each socket in socket io is identified by a random unguessable unique identifier socket id for your convenience each socket automatically joins a room identified by its own id.
A socket is the fundamental class for interacting with browser clients.
I have a problem regarding the handling of multiple chat rooms.
Socket io provides additional features over a plain websocket object which are listed below.
However the problems is that the connection is persistent and i wish to address the problem by using the socket leave room method.
But first let s detail what the socket io library is not.
This wasn t overridden by the redis adapter so you re actually querying the base adapter which only knows about rooms clients in the current process.
A socket belongs to a certain namespace by default and uses an underlying client to communicate.
Additonally if rooms list is temporary you can clean it whit controlled event after disconnecting.
Push data to clients that gets represented as real time counters charts or logs.
Where you can save socket id or other identifier with rooms.
In disconnect event you can query this object to know the rooms you have to leave.
Can i use wildcards in events.
Rooms are used to further separa.
Prevent flooding from single connection.
It works on every platform browser or device focusing equally on reliability and speed.
Not in socket io directly but check out this plugin by hao kang den.
It provides a socket io middleware to deal with wildcards.
What socket io is not.
To leave a channel you call leave in the same fashion as join both methods are asynchronous and accept a callback argument.
My question is how can this be handled on the client side.
Limit number of events by ip uniqueuserid or and socket id with rate limiter.
Within each namespace you can also define arbitrary channels called room that.
Socket io rooms within each namespace you can also define arbitrary channels that sockets can join and leave.
If you are using some db o nosql you can save it for distributed environments.
These channels are called rooms.
Any of the above examples specific to versions mentioned above you are querying the rooms property on socket io redis adapter.
